Merge branch 'pm-cpufreq'pm-6.10-rc3
Merge cpufreq fixes for 6.10-rc3: - Fix a recently introduced unchecked HWP MSR access in the intel_pstate driver (Srinivas Pandruvada). - Add missing conversion from MHz to KHz to amd_pstate_set_boost() to address sysfs inteface inconsistency (Dhananjay Ugwekar). - Get rid of an excess global header file used by the amd-pstate cpufreq driver (Arnd Bergmann). * pm-cpufreq: cpufreq: intel_pstate: Fix unchecked HWP MSR access cpufreq: amd-pstate: Fix the inconsistency in max frequency units cpufreq: amd-pstate: remove global header file
